manufacturer’s specification due to the actual load on that wheel
position. Some vehicles may have different sized tires mounted on the
front and rear axles, and these different sized tires have rotation
restrictions. Always check the vehicle Owner’s Manual for the proper
rotation recommendations.
FULL-SIZE SPARE
Full-size spare tires (not temporary spares) of the same size and
co
nstruction should be used in a five tire rotation. Always check the
inflation pressure of the full-size spare immediately before
incorporating it into rotation. Follow the vehicle manufacturer’s
recommended pattern for rotation, or if not available, see a qualified
tire technician.
REPLACEMENT OF TWO TIRES
It is recommended that all four tires are replaced at the same time.
Ho
wever, whenever only two tires are replaced, the new ones should
be put on the rear. The new tires, with deeper tread, may provide
better grip and water evacuation in wet driving conditions.
CUSTOMIZATION OF TIRES, WHEELS, OR SUSPENSION ON
SU
VS AND LIGHT TRUCKS
Due to their size, weight and higher center of gravity, vehicles such as
SU
Vs and light trucks do not
have the same handling characteristics
as automobiles. Because of these differing characteristics, failure to
operate your SUV/truck in a proper and safe manner can increase the
likelihood of vehicle rollover. Modifications to your SUV/truck tire
size, tire type, wheels or suspension can change its handling
characteristics and further increase the likelihood of vehicle rollover.
Whether your SUV/truck has the original equipment configuration
for tires, wheels and suspension or whether any of these items have
been modified, always drive safely, avoid sudden, sharp turns or lane
changes and obey all traffic laws. Failure to do so may result in loss of
vehicle control leading to an accident and serious injury or death.
TIRE ALTERATIONS
Do not make or allow to be made any alterations on your tires.
Al
terations may prevent proper performance, leading to tire damage
which can result in an accident. Tires which become unserviceable due
to alterations such as trueing, whitewall inlays, addition of balancing
or sealant liquids, or the use of tire dressing containing petroleum
distillates are excluded from warranty coverage.

REPAIRS - WHEREVER POSSIBLE, SEE YOUR BFGOODRICH®
TIRE RETAILER AT ONCE
If any BFGoodrich® tire sustains a puncture, have the tire demounted
an
d thoroughly inspected by any BFGoodrich® tire retailer for
possible damage that may have occurred.
A tread area puncture in any BFGoodrich® passenger or light truck
ti
re can be repaired provided that the puncture hole is not more than
1/4” in diameter, not more than one radial cable per casing ply is
damaged, and the tire has not been damaged further by the
puncturing object or by running underinflated. Tire punctures
consistent with these guidelines can be repaired by following the
Rubber Manufacturers Association (RMA) recommended repair
procedures.
TIRE REPAIRS
Repairs of all tires must be of the combined plug and inside patch
t y
pe. Plug only repairs are improper. A tire should be removed from
the rim and inspected prior to repair. Any tire repair done without
removing the tire from the rim is improper. An improperly repaired
tire will cause further damage to the tire by either leaking air or
allowing air, moisture and contaminants to enter the structure of the
tire. An improperly repaired tire can fail suddenly at a later date.
Never repair a tire with less than 2/32 nds of an inch tread remaining.
At
this tread depth, the tire is worn out and must be replaced.
TEMPORARY SPARE TIRES
When using any temporary spare tire, be sure to follow the vehicle
ma
nufacturer’s instructions.
READING THE DOT
DOT XXXX XXXX XXX (prior to August 2000)
DOT XXXX XXXX XXX (1990-1999)
DOT XXXX XXXX XXXX (after July 2000)
THE DOT
The “DOT” symbol certifies tire manufacturer’s compliance with US
De
partment of Transportation (DOT) tire safety standards. Next to the
symbol is the tire identification or “serial number”. The first two
characters identify the plant where the tire was manufactured. The
next two characters reflect the tire size. The following one to four
digits may be used at the tire manufacturer’s option as a descriptive
BFGOODRICH® TIRES
39
code. The last three characters are numbers identifying the week and
year of manufacture. Example: “O25” means second week of the year
of decade, eg.: 1995, 1985, etc. Tires produced after July 2000 have an
additional digit to identify a given decade. For example, 2800 means
th
e tire was produced during the 28th week of 2000; 0201 during the
2nd week of 2001. If the last digits of your DOT number contain three
numeric characters consult a qualified tire technician to determine the
year and decade of manufacture.
STORAGE
Tires contain waxes and emollients to protect their outer surfaces from
oz
one and weather checking. As the tire rolls and flexes, the waxes
and emollients continually migrate to the surface, replenishing this
protection throughout the normal use of the tire. Consequently, when
tires sit outdoors, unused for long periods of time (a month or more)
their surfaces become dry and more susceptible to ozone and weather
checking and the casing becomes susceptible to flat spotting.
For this reason, tires should always be stored in a cool, dry, clean,
in
door environment. If storage is for one month or more, eliminate the
weight from the tires by raising the vehicle or by removing the tires
from the vehicle. Failure to store tires in accordance with these
instructions could result in damage to your tires or premature aging
of the tires and sudden tire failure.
When tires are stored, be sure they are placed away from sources of
he
at and ozone such as hot pipes and electric generators. Be sure that
surfaces on which tires are stored are clean and free from grease,
gasoline or other substances which could deteriorate the rubber.
(Tires exposed to these materials during storage or driving could be
subject to sudden failure.)
FOLLOW THESE MOUNTING RECOMMENDATIONS
Tire changing can be dangerous and must be done by professionally
tr
ained persons using proper tools and procedures as specified by
the Rubber Manufacturers Association (RMA).
Your tires should be mounted on wheels of correct size and type and
wh
ich are in good, clean condition. Wheels that are bent, chipped,
rusted (steel wheels) or corroded (alloy wheels) may cause tire
damage. The inside of the tire must be free from foreign material.
Have your retailer check the wheels before mounting new tires.
Mismatched tires and rims can explode during mounting. Also,
mismatched tires and rims can result in dangerous tire failure on the
BFGOODRICH® TIRES
40
road. If a tire is mounted by error on the wrong-sized rim, do not
remount it on the proper rim — scrap it. It may have been damaged
internally (which is not externally visible) by having been
dangerously stretched and could fail on the highway.
Old valves may leak. When new tubeless tires are mounted, have
ne
w valves of the correct type installed. Tubeless tires must only be
mounted on wheels designed for tubeless tires i.e., wheels which
have safety humps or ledges.
It is recommended that you have your tires and wheels balanced. Tires
an
d wheels which are not balanced may cause steering difficulties, a
bumpy ride, and irregular tire wear.
Be sure that all your valves have suitable valve caps. The valve cap
is
the primary seal against air loss.
SERVICE LIFE FOR PASSENGER CAR AND LIGHT TRUCK TIRES
IN
CLUDING SPARE TIRES
The following recommendation applies to passenger car and light
tr
uck tires. Tires are composed of various types of material and rubber
compounds, having performance properties essential to the proper
functioning of the tire itself. These component properties evolve over
time. For each tire, this evolution depends upon many factors such as
weather, storage conditions, and conditions of use including load,
speed, inflation pressure, maintenance etc. to which the tire is
subjected throughout its life. This service-related evolution varies
widely so that accurately predicting the serviceable life of any specific
tire in advance is not possible.
In addition to regular inspections and inflation pressure maintenance
by
consumers, it is recommended to have passenger car and light
truck tires, including spare tires, inspected regularly by a qualified tire
specialist, such as a tire dealer, who will assess the tire’s suitability for
continued service. Tires which have been in use for five years or more
should continue to be inspected by a specialist at least annually.
Consumers are strongly encouraged to be aware not only of their tires’
vi
sual condition and inflation pressure but also of any change in
dynamic performance such as increased air loss, noise or vibration,
which could be an indication that the tires need to be removed from
service to prevent tire failure.
BFGOODRICH® TIRES

It is impossible to predict when tires should be replaced based on their
calendar age alone. However the older a tire the greater the chance
that it will need to be replaced due to the service-related evolution or
other conditions found upon inspection or detected during use.
While most tires will need replacement before they achieve 10 years,
it
is recommended that any tires in service 10 years or more from the
date of manufacture, including spare tires, be replaced with new tires
as a simple precaution even if such tires appear serviceable and even
if they have not reached the legal wear limit.
For tires that were on an original equipment vehicle i.e., acquired by
th
e consumer on a new vehicle, follow the vehicle manufacturer’s
tire replacement recommendations, when specified (but not to
exceed 10 years).
The date when a tire was manufactured is located on the sidewall of
ea
ch tire. Consumers should locate the Department of Transportation
(DOT) code on the tire which begins with DOT and ends with the
week and year of manufacture. For example, a DOT code ending with
"2204" indicates a tire made in the 22nd week (May) of 2004.
